Letters PatentNo. 112,861, dated March 21, 1871.

lMPROVEMENT IN GAUGES FR SAW-TABLES.

The Schedule referred to in these Letters Patent and making part oi' thesame.

I, FRANKLIN L. SPRAGE, of Keene, in the county of Cheshire, in the Stateof New Hampshire, have invented certain Improvements in Gauges for Saw-Tables, of which the following is a speciiicatin'n.

rlhe object-ot -this invention is to furnish to those interested acheap, simple, and, at the same time, an effective gauge for sawingstuii" of different dimensions, and that can be applied to eithercircular, reciprocating, and other saws; that is quickly adjusted todif'- i'erent sizes of' stuff, and can be quickly detached from orattached to the table, and, when detached, leave the top of the tablesmooth, and without grooves, holes, or slots; and

It consists in the construction of the gauge, and allows of itsadjustment upon and its removal from the saw-table, and themanner ofattaching the gauge to.

the table, and the location of the gauge upon the table.

In the drawingv Figure 1 is a top view of the table and the gauge;

Figure 2 is a side view of the same; and

Figure 3 is an end view of the same.

A isthe saw-table, of the usual form, and having the usual slit, a, inwhich the saw works.

A is the sliding removable saw-gauge, composed of parts B, B', and G.

B is the face or upright part of thegauge, and B' is the horizontal partoi' the gauge, which gives to it strength, and rests .upon table A.

C is an upright face-plate, firmly attached to the cndsof parts B andB', with the portion b acting as a strengthening-brace to the gauge.

Upon the inner side, on the side plate C, is a wide dovetail groove, ce.

` Centrally located in plate C isa screw-hole, which receives theholding-screw E.

The parts B, B', and C may he made in a single piece by casting, or thegauge may be made of several parts joined together in an'y securemanner; or it may be made entirely of wood, or part wood and part metal,but metal is preferable.

D is a slide-way for the gauge to slide and-be adjusted upon, andissecurelyattached -to the edge of saw-table. This slide-way has anupright face-plate on the end or edge of the table, and a flangeprojecting at right angles to its face that extends under the table, andby which it is made fast and secured to the under side ofthe saw-table.

'.lhel upright face-plate has its top and bottom edges made angular, soas to closely fit into the wide dovetail groove c c in part C, but notfitting so-close as to prevent its sliding easily upon the slide-way,yet, by the part C being so long in its bearing upon the slide.-

way, the gauge will be always true and at right angles with the face ofplate D.

Upon the face of plate D is a graduated scale, by which the widthbetween the face of the gauge and the side ot' the saw next the gaugecan be readily known.

v Eis the holding-screw, that, when turned. in and through thescrew-hole in part C, and against the face of plate or slide-way D, thegauge will be lfirmly and truly held in propel' position.

It' the saw-table is of metal, cast or wrought, the slide-way or part dmay be madeon the edge or side of such metal table, and be a part of thesame.

By this construction of the table and gauge the gauge is quicklyadjusted to. any desired position on the table; it eau also be instantlyremoved from the table and leave the table free and withoutanyappendage, as it is attached to and slides upon a way that is locatedbelow the top or face of the table, leaving neither grooves, holes, orslots in the top or through the table, in which dust or chips will finda restingplace to annoy the tender.

Thegauge can be attached to either end or edge of a table, as may bedesired. It is composed of few parts, and without danger of being putout of order if properly attached to the table, and will always hereliable for the purposes intended. It is cheap and durable.

I lay no claim to either the construction or what is claimed as theinvention in the patent granted to Behel and Nelson February 13, 1867;nor do I claim, for the construction shown in a drawing representing aninvention in saw-benches by one William Furness,

Aof Liverpool, England, as neither of those inventions is the same aswhat is vdescribed as the invention in this application.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is

Il. 'lfhe sliding removable saw-gan e A', constructed Witnesses:
